Helen (Vision:Impossible)

Helen is a disgruntled former docent at the American Safety Museum.

After getting discount coupons in the paper, the family spends the day at the museum despite Roger's vision of the future that havoc awaits at the museum in "Vision: Impossible". Their day is interrupted when Helen arrives to shoot up the place and sets the museum on fire. With most of the equipment props and no real safety precautions taken at the museum, Roger directs them in the right course of action and they escape the carnage.
